The above statement is a disclaimer so there’s no question in anyone’s mind - I am not an expert on printing. I’ve subscribed to the ArgyllCMS mailing list for maybe ten years now, so I end up reading a lot of posts about printer profiles, but that doesn’t make me an expert! There is a great big huge gap between reading and doing!
One question I have, and maybe someone who really is an expert (translate: has actual experience profiling a printer and using the profile) can answer:
When you make a printer profile, is the printer profile used only for soft proofing? Or do you also convert the image from its RGB working space to the printer profile before feeding the image to the printer? Or does this vary depending on the printer? Various commercial printing places do supply soft proofing profiles, but they don’t usually want the image actually converted to the soft proofing profile when you send them a digital file.
